I'm sure MMDF could be attacked with stack overwrites and strcpy(3) style attacks because when Crocker wrote it, that was not what was being considered. =E1=90=A7 On Mon, Jun 25, 2018 at 12:10 PM, Noel Chiappa wrote: > > From: Clem Cole > > > the MTA part is not there > > That system was using the MMDF MTA: > > https://minnie.tuhs.org//cgi-bin/utree.pl?file=3DSRI-NOSC/mmdf > > written by David Crocker while he was at UDel (under Farber). > > Noel > > --00000000000003d91c056f7ad75b Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

That system was using the MMDF MTA:
